Standard Motor Products TH345 Throttle Position Sensor (TPS) OE Replacement

The Standard Motor Products TH345 is a direct-fit, OE-replacement throttle position sensor (TPS) engineered to restore precise throttle feedback to your vehicle's engine management system. Designed to match original equipment specifications, this sensor delivers the accurate output signals your powertrain control module (PCM) requires for proper idle control, fuel delivery, and throttle response.

How It Works:

The throttle position sensor monitors the angle and movement speed of the throttle valve, converting that mechanical position into an analog voltage signal. The PCM uses this signal to determine optimum fuel enrichment, fuel cut during deceleration, and idle stabilization — making a properly functioning TPS critical to overall driveability and fuel efficiency.

Key Features:

• OE-Specific Output: Calibrated to match the factory-installed output voltage — not an adjustable consolidated design — for a true plug-and-play replacement
• Precision Circuit Substrates: Circuits printed on flexible polyimide film or ceramic-based substrates for excellent dimensional stability and resistance to electrical performance drift
• Noble Metal Alloy Contacts: Palladium/gold/platinum alloy contact surfaces provide ultra-low contact resistance and extended service life
• Integral Rotor Bearings & Return Springs: Built-in bearings and return springs simplify installation and ensure consistent mechanical operation
• End-of-Line Tested: Every sensor undergoes rigorous testing with thousands of data points to validate output voltages before leaving the factory
• Direct OEM Replacement: Engineered to meet or exceed original equipment specifications for a reliable, trouble-free repair

Standard Motor Products is a trusted name in the automotive aftermarket with over 100 years of experience supplying OE-quality sensors and ignition components. The TH345 throttle position sensor is sold individually and is designed for straightforward installation without modification.
